Livestream‘s Studio HD51 4K Live Production Switcher is an all-in-one, broadcast-quality, 5-input switcher with pre-installed Livestream Studio production software. Connect up to five HDMI or professional SDI sources and stream to in-venue screens or to the web using the built-in HD multi-bitrate encoder. The HD51 4K is built to perform with a 3.2 GHz eight-core Intel Core i7 processor, 64GB of RAM, and 2TB of SSD storage capable of recording four simultaneous isolated (ISO) recordings or 40 hours of broadcast-quality HD video. Using the included rack ears, the HD51 4K can be rack-mounted in 2U of rack space, making it suitable for studios, production facilities, live venues, and production trucks. Also included is a twelve-month telephone support plan, a configurable, color-coded Livestream production keyboard, a mouse with mousepad, and power cord.

The HD51 4K is designed to broadcast television SMPTE and color sampling standards, supporting formats up to 1080p30/25 and 1080i60/50 and featuring 10-bit 4:2:2 video and 24-bit 48 kHz audio processing. Five Blackmagic Design DeckLink Mini Recorder 4K cards provide support for five inputs sources, with each input available as HDMI or SDI. A Blackmagic Design DeckLink Mini Monitor 4K provides an HDMI and SDI output. Two remote camera sources, such as a live feed from your Livestream account and a remote computer desktop, as also supported, providing a total of seven live inputs. The HD51 4K supports embedded audio from SDI and HDMI input sources, as well as analog audio via a 1/8″ input. Audio monitoring is available via a 1/8″ output.

The pre-installed Livestream Studio live production software provides a full field rate multiview that displays all live inputs, graphics, and media players in real-time. The multiview features audio monitoring for each input and audio PPM overlay with peak hold on all inputs and outputs. The integrated NVIDIA GeForce GT 730 graphics card lets you extend your display to two additional monitors via HDMI and DVI connectors. In terms of graphics, two layers can be overlayed and mixed with transparency. Add text, images, live picture-in-picture, countdown graphics, and more.

Facebook Live Compatibility

Previously open only to mobile devices, Livestream’s HD51 can broadcast professional productions straight to Facebook. Log-in and go live.

Chrome Browser-Based Control

Open up Google’s Chrome browser (available free for Windows, OSX, Chromebook, and Android devices) to control Livestream’s studio software remotely.

Bonded Streaming

By leveraging multiple connections, including Ethernet, WiFi, and 3G/4G LTE, you can spread your stream bandwidth for a more reliable connection. You can also set up alternate backup connections in case your primary connection fails or becomes too slow.

Virtual Camera Crop

Use a single 4K input to generate multiple camera angles. A simple interface lets you divide up the master source into several 1080p or 720p “virtual cameras” that can be panned and tilted in the virtual space. Cuts and transition presets are also supported for extra production value.

Built-In Multiview

Monitor all your cameras in real-time thanks to the built-in multiviewer. The multiviewer features on-screen full field rate multiview of all live inputs, Preview, Program Out, two GFX and two DDR, and Audio PPM overlay with peak hold feature on all inputs and outputs. The layout is resizeable to allow for hiding of all controls to maximize multiview screens.

Cut, dissolve, or select from a collection of SMPTE wipes, with feathering and positioning control. Fade time durations can be manually adjusted in frames via the on-screen T-BAR or keyboard shortcuts.

Built-In Audio Mixer

The integrated multi-channel audio mixer features mix automation, SDI and HDMI embedded audio, level monitoring, peak warnings, as well as channel grouping. The incorporated video switcher follow feature supports audio crossfade when fading between two video sources. The HD51 also supports the use of external audio mixers.

Audio Input Options

The HD51 supports embedded audio via SDI or HDMI inputs. You can also bring in separate analog audio using the 1/8″ input, or from any USB audio device.

Built-In Graphics Editor

The 2-channel graphics generator is built-in the GUI and allows you add text, transparent images, live picture-in-picture video, countdowns, and a range of graphic effects including drop shadows, borders, crops, and more. Create templates to quickly change sport scores, lower third text, or other graphic elements on-the-fly.

Downstream Key Overlays

Overlays graphics as layers on top of your program mix with transparency. This is ideal for adding corner bugs, sport cording, lower thirds, picture-in-picture, and other broadcast graphics.

Picture-In-Picture

Composite up to five live audio/video sources together within the graphics editor. Add a simple second camera angle, a scoreboard cam, or even a broadcast network 4-person live chat over an animated background video.

Media Recording (With ISO Recording)

Record your program output in broadcast quality MJPEG to an AVI file for archive and editing later in your NLE software, or for playback directly within one of the Livestream Studio media players. The HD51 supports up to four simultaneous isolated recordings (ISO). Choose from clean graphics-free video, video with graphics, as well as any live camera input. You can also open the files being recorded in the media players to trim and replay segments from your live show without stopping the recording.

Livestream Studio Media Player

Add recorded material to your program quickly and easily with the two media players built-in to Livestream Studio. You can import popular media formats such as H.264 video, MP3 and WAV audio), build playlists, loop clips, and auto-play on transition. You can also scrub through footage and trim clips down for broadcast. When working with clips that do not match your project settings, the built-in transcoder is available for file conversion. You can even get basic instant-replay functionality by loading an ISO recording into the media player.

Recording

The HD51 supports four simultaneous recordings. Record up to 40 hours of 1080i video at 100 Mbps in AVI MJPEG with uncompressed audio to the internal 2TB SSD. Interlacing and “Time of Day” timecode are supported. Recording is fully compatible with Blackmagic Design Media Express and Adobe Premiere.

Remote Camera

Desktop: Broadcast a remote computer desktop video and audio as a Livestream Studio input via your local Wi-Fi or Ethernet network. Full motion and audio are supported.

Cloud: Downlink live feeds from your Livestream accounts and use it as a remote live source in your program mix.

Integrated Live Streaming Encoder

Livestream Studio comes with a built-in H.264/AAC multi-bitrate live streaming encoder. You can stream HD video directly to Livestream, UStream, YouTube Live, or any RTMP-compatible server or CDN (Wowza Media Server, Akami, Flash Media Server). Also supported is the ZiXi streaming protocol and 1080p streaming when using custom quality settings.

Output your live program via SDI or HDMI to large format in-venue screens, broadcast networks, or complement your workflow using external video hardware such as graphics generators, encoders, and recorders.

Tally Light

Use the tally light integration to let your talent and camera operators know which source is live and which source is coming next. The HD51 supports tally devices from MetaSETZ.
